the function header. All functions are defined before use. Name constructors and callback functions as much as possible, so that you can see a clearer call stack during debugging. Try to define all member functions in the constructor through the prototype, define the attributes in the constructor, and then use the new keyword to create an object for the constructor. Avoid complex inheritance. If you want to inherit, use the inherits function in the util module whenever possible. For example

The scope of a variable is nothing more than two kinds: global and local variables. The special point of the JavaScript language is that the global variable can be read directly from within the function. JS
